FM Synthesis - A Practical Guide - Part 1

video upload by ChrisLody

"Here's something I've been meaning to get round to starting for ages, a practical guide to FM synthesis. In my experience FM tutorials usually over explain all the wrong things and rarely get as far as the important things like the predictable way operator ratios change the waveform and frequency responses. So I've tried to approach things from an entirely practical view point showing you how to make saw, square, noise etc with filter like responses.
